Preseeding the installer?

Question

I need to preseed a dual boot installation of Ubuntu 10.04. I want partman to use all already existing Linux partitions and all free space (like the option when installing Fedora 13). what would that recipe look like?

Answer 1

You need an unattended install. A couple of approaches here: https://help.ubuntu.com/community/Installation/UnattendedCD http://www.linuxuser.co.uk/tutorials/unattended-ubuntu-installations

Answer 2

AFAIK you cannot reuse partitions, you only can use the space left non partitioned or use the whole disk (deleting all the data living in the disk), you're looking for the options:

 # other possible choices: regular, lvm, crypto
 d-i    partman-auto/method string regular

 # other possible choices: atomic, home, multi
 d-i     partman-auto/choose_recipe select multi

 #d-i     partman-auto/expert_recipe string
